To assess the role of sexual relationships on levels and patterns of adherence to medication for pre-exposure prophylaxis against HIV.
We enrolled 1147 HIV-negative individuals in long-term serodiscordant relationships at 3 sites in Uganda from the Partners Pre-exposure Prophylaxis Study, a randomized placebo-controlled trial of daily oral tenofovir and emtricitabine/tenofovir. We used generalized estimation equations to assess the effects of sexual relationships on low adherence (<80%) and on gaps in adherence.
Fifty-three percent were male, 51% were 18-34 years and 24% were polygamous. Participants who reported sex in the past month with someone other than their primary partner and with <100% condom use were more than twice as likely to have low adherence [adjusted odds ratio (aOR) = 2.48, 95% CI: 1.70 to 3.62] compared with those who had sex with only their primary partners and 100% condom use. Using the same reference group, those who abstained from sex in the previous month had 30% increased odds of low adherence (aOR = 1.30, 95% CI: 1.05 to 1.62) and participants in nonpolygamous marriages who reported sex with both their primary and other partners and <100% condom use were almost twice as likely to be low adherers (aOR = 1.76, 95% CI: 1.01 to 3.08). At least one 72-hour gap in adherence was seen in 598 participants (54.7%); 23.2% had at least one 1-week gap.
Risk of low overall adherence was higher in participants who reported sex outside primary partnerships and suboptimal condom use, as well as in those who abstained from sex. Adherence gaps were common, potentially creating risk for HIV acquisition.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 May 2015.
All research outputs
#24,275,229
of 34,601,305 outputs
Outputs from JAIDS: Journal of Acquired Immune Deficiency Syndromes
#4,925
of 6,011 outputs
Outputs of similar age
#200,105
of 307,432 outputs
Outputs of similar age from JAIDS: Journal of Acquired Immune Deficiency Syndromes
#68
of 91 outputs
Altmetric has tracked 34,601,305 research outputs across all sources so far. This one is in the 28th percentile – i.e., 28% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,011 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.5. This one is in the 16th percentile – i.e., 16% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 307,432 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 91 others from the same source and published within six weeks on either side of this one. This one is in the 24th percentile – i.e., 24% of its contemporaries scored the same or lower than it.
